vst~ and identifying parameter changes

Ive noticed in the vst~ that when I change presets in the vst, the parameter values are not updated. . This means that any sliders connected to the vst cannot update when a preset is selected within the vst. Is this the intended behaviour of vst~ or is it a feature that just hasnt been added?

I realise I can get each parameter, however, its impossible to know when to get these parameters, if the vst~ object is not telling me changes are being made in the vst.
